Application filed March 23, 1921.

T 0 all whom it may concern:

Be it known that we, LOUIS Mann and PETE BIALY, citizens of the UnitedStates,

in the county of Multnomah, in the State of Ore on, have inventedcertain new and useful mprovements in Spring ll heels, of which thefollowing is a specification. a

' his invention relates to vehicle wheels of the resilient class, andhas for one of its objects to provide a wheel having curved resilientspokes so arranged that they mutui ally support and reinforce eachother.

trating Another object of the invention is to provide a device'of thisrim and plurality of spring spokes attached tothe rim and to the hub anddetachably held, so that any individual spoke may be detached or appliedas required. i

lVith these and-other objects in view the invention consists of certainnovel features of construction as hereinafter shown and described, andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention: I r Figure 1is a side elevation, partly in section, of the improved wheel.

Fig. 2 is a section on the line 22 of Figure l.

Fig. 3is an enlarged section detail illusthe manner of coupling thespokes to the rim.

Fig. 4 is a sectional detail illustratinga' modificationin theconstruction.

The improved wheel includes a rim, a hub of novel construction and aplurality of spring spokes of novel construction,.so ar ranged andunited that any individual spoke can be detached or replaced withoutdisturbing the other parts.

The hub of the improved wheel comprises a body portion 10 adapted toengage the axle journal, not shown, and provided with a plurality ofcurved seats 11' opening through the periphery ofjthe body and likewiseat one side, and a bearing plate 12 attached to the body 10 by clampbolts 13.

The rim of the improved wheel is represented as a whole at '14, Whilethe tire may be of the pneumatic form as shown at 15 in Figs. 1 and 2,or the improved spokes Specification of Letters Patent;

7 character including a: a hub of separable parts and a.

coupled to the rim, the

Patented Feb. 21, E922. Serial No. 454,963.

may be applied to the ordinary felloe 16 an ordinary wheel, as shown inFi 1.

The spokes of the improved w lieel are each formed of a section ofresilient material, preferably of steel, and each comprises a curvedbody portion 17 engaging by their inner en s respectively in the sockets11 as illustrated in Figure 2, and with their outer portions curvedinwardl toward the hub as shown at 18 with the curved portions bearinagainst the inner face of the rim and the terminals 19 reversely curvedto COIIfOlII'l to and bear against the adjacent face of the next bodyportion 17.

At the point where the curved portion 18 engages the rim .14 the rim isprovided with a socket indicated at 20 in Fig. 8, and each curvedportion 18 provided with an integral lug or projection 21 engaging inthe socket. The spokes are secured to the rim by fastening devices suchas bolts 22 passing through the 21 and tapped into the rim 14: as shownin F ig. 3. a By this -means the spokes are firmly bolts holding thespokes from inward displacement, and the lugs holding them from lateraldisplacement and likewise preventing shearing strains on the bolts.

The spoke members are initially so curved that considerable force willbe required to dispose the spokes in position, thus insurin therequisite reactionary force to hold them in place, and likewise toprovide the necessary resiliency to the wheel.

he curvature of the portion 18 of the spokes may be increased ordecreased to correspondingly increase or decrease the resistance orstillness of the spokes, to correspond to the vehicle and the load whichit is constructed to carry.

his is an important feature of the improved device and materiallyincreases the efficiency and utility ofthe device.

The device is simple in construction and can be inexpensivelymanufactured and applied without material structural change to wheels ofvarious forms and sizes.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be run derstood that anymodifications Within the scope of the claims may be made in theconstruction without departing from the principle of the invention orsacrificing any of its advantages.

Having thus described the invention What is claimed as new is A vehicleWheel including a rim and hub,

resilient spokes attached at'their inner ends a to the hub and bentintermediate the ends and directed toward the hub and attached:-

at the bent portion to the rim, the terminals of the bent {portion beingunattached and frictionally engaging the body portion of the next spokein advance and reinforcing 1n the same. 7 a V a In testlmony whereof, Weaffix our Signatures hereto,
